Wi-Fi 6 Overview – Next Generation Wi-Fi 802.11ax


Wi-Fi 6 – 802.11ax 

Wi-Fi 6 is an advance next generation wireless technology called 802.11ax which provides fastest network connectionHigh density performance and Energy saving efficiency to end users computing systems.

Wi-Fi 6 is an advance (Wi-Fi Alliance) industry certification program devolved under the IEEE 802.11ax standard builds and improves on the current 802.11ac Wi-Fi standard. Wi-Fi 6 is capable of achieving a top speed of 9.6 Gbps, improved from 3.5 Gbps on Wi-Fi 5.

Wireless technology is a backbone of everyday life at office, work place, home, public place, traveling included  every smartphone, computer, tablet, IoT Devices everywhere Wi-Fi capability is now a requirement for a growing range of devices simply have a large number of devices in your household and appliances to security systems.

Wi-Fi 6 originally built in response to the growing number of devices in the world, Wi-Fi 6 device break down how they’re faster, increase efficiency, and are better at transferring data than previous generations.

In today time, the users need for higher density, higher throughput and higher capacity are critical to wireless networks. Wireless Network demand are rapidly growing and the numbers are increasing every year. Ends users device need freedom of mobility network connection with superfast internet connection over multiple smart devices, Application, video, Smart Television and other IOT devices etc, these are the things that everyone wants from their wireless network

Wi-Fi 6 delivers improvements and new features that enable Wi-Fi 6 devices to operate efficiently, even in dynamic environments and supporting a large variety of device types, helps bring the promise of connecting everyone and everything, everywhere, closer to reality.

Three main Benefits of Wi-Fi 6 –

Wi-Fi 6 High density performance

The user demand of wireless uses are rapidly increasing such area government’s offices, School and college campuses, event venues and everywhere. The Wi-Fi passion of hundreds or thousands of users puts a huge stress on these limited Wi-Fi networks, which often aren’t equipped to handle so many users, overlapping wireless signals, and data-hungry applications.

Wi-Fi 6 perform dramatically better high density performance. Wi-Fi 6 AP and Router use a diversity of technologies to avoid interference between devices and transmit packets more efficiently and the outcome is more resilient networks that continue to deliver fast speeds even as more devices connect to the network.

Wi-Fi 6 Faster Speeds

As per industry experts is that Wi-Fi 6 will offer speeds that are roughly 30 to 40% faster than Wi-Fi 5 generation with theoretical maximum transfer speeds up around 9.6 Gbps*.

Wi-Fi 6 will help to deliver more consistent performance across a large number of devices and also faster speeds to every device. 

Wi-Fi 6 Energy Efficiency

Wi-Fi 6 enables greater energy efficiency by reducing the battery burden on devices connected to the wireless network. Wi-Fi 6 introduce a new feature called Target Wake Time (TWT), significantly improves battery life in Wi-Fi devices. Target Wake Time enables devices to monitor when and how frequently they will wake up to send or receive data.TWT can help devices achieve up to 67% lower power consumption.
